Go with what you can afford, that is what I've always done and I love my 02 dodge. The VP44 isn't an issue if you buy a good liftpump upgrade like a airdog or FASS system, the common rail dodges need upgraded fuel systems to. If you go with a 24v truck with an auto plan on a TC and VB upgrade if your looking for full potential, if you plan on racing or sled pulling look into a full tilt built tranny. I like the 24v cause it is affordable for most, easy to find parts for, plan on sinking 3 grand into one with an auto to get 300-350 on the ground and it hold together:filter,exhaust,chip,fuel system,injectors,TC and VB. Don't forget guages if you don't get a monitor with your chip.
